In nes_create_qp(), the test
if (nesqp->mmap_sq_db_index > NES_MAX_USER_WQ_REGIONS) {
is used to error out if the db_index is too large; however, if the
test doesn't trigger, then the index is used as
nes_ucontext->mmap_nesqp[nesqp->mmap_sq_db_index] = nesqp;
and mmap_nesqp is declared as
struct nes_qp *mmap_nesqp[NES_MAX_USER_WQ_REGIONS];
which leads to an array overrun if the index is exactly equal to
NES_MAX_USER_WQ_REGIONS. Fix this by bailing out if the index is
greater than or equal to NES_MAX_USER_WQ_REGIONS.
This was spotted by the Coverity checker (CID 2162).
